“Most countries are simply not ready. They do not have policies to protect the rights of local and indigenous peoples, to determine land tenure or even work out who owns the ‘carbon rights’ to a forest,” Larson told participants at an international conference on smallholder and community forestry in Montpellier, France, in late March.

Under the REDD initiative, richer countries would pay to maintain forests in tropical regions to offset their own carbon emissions. Carbon dioxide from human activities is one of the main gases that produce the greenhouse effect.
